Reference News Network reported on July 20. Spain's "El Pais" reported on July 18 that although the elders continue to instill some so-called nutrition "legends" to their younger generations, many of the claims have no scientific basis and are purely exaggerated. The newspaper listed 6 common dietary misunderstandings:
1. Breakfast is the most important meal of the day
Although we cannot say that this sentence is completely wrong, nothing can be said so absolutely. Because there is no so-called most important meal of the day, eating breakfast will not significantly help weight loss, and breakfast does not distinguish between an "ideal" breakfast and a "bad" breakfast.
If you put too much emphasis on breakfast, you will ignore the status of the other two meals. It is only a speculation that eating breakfast helps lose weight, and there is no clear scientific basis to prove it. There are countless combinations of breakfast options, and no one is ideal. The so-called ideal breakfast food manufacturers recommend to consumers is actually the product they want to sell you.
There are indeed many foods in this world that are beneficial to the human body, but these benefits have nothing to do with when you eat them. So don’t be fooled by the ads, good foods don’t become bad just because you don’t eat them in the morning. What to eat for breakfast should be chosen according to your own situation. It does not mean that what is recommended by advertisements is the best for you.
2. Drinking a glass of milk can help you sleep
The theory that drinking milk can induce hypnosis is widely circulated because the tryptophan contained in milk is an amino acid necessary for the synthesis of serotonin and melatonin, and both neurotransmitters serotonin and melatonin are related to Related to sleep cycles. But in fact, the tryptophan content in milk is far from enough to have an effect on the human sleep cycle.
In addition, the tryptophan in milk is absorbed and regenerated into serotonin and melatonin, a process that takes several days. Assuming that the tryptophan in milk really promotes sleep, why don't you fall asleep for several days after drinking a glass of milk?
3. Dieting helps to lose weight
Many people who are troubled by obesity have been advised to diet. However, in fact, instead of losing weight, dieting can actually increase the risk of obesity. In other words, the more you diet, the more you gain weight.
The real way to lose weight is to have a balanced diet, not to diet. A diet may work initially, but the weight lost will quickly come back on. Dieting can only make usThe brain craves food more, ultimately trapping us in a vicious cycle from dieting to bingeing to dieting again.
4. Meat is the food with the richest protein content
Although meat is indeed a food rich in protein, it also depends on the situation-some meat has an extremely high fat content. Among many types of meat, fish is a good choice for protein supplement. But what is certain is that meat is by no means the most protein-rich food.
Overall, the protein content per unit of beans is the highest among foods. Under normal circumstances, the protein content of meat is between 16% and 21%, while the proportion of beans is as high as 22% and 36%.
5. Vitamin C supplementation can prevent or treat colds
According to many nutritional legends, vitamin C is endowed with magical powers - not only can it prevent colds, but it can also promote the recovery of colds. However, in fact, there is no reliable scientific basis to prove this to date. Although some studies have shown that long-term use of vitamin C can shorten the duration of cold symptoms, this conclusion has not yet been supported by a large number of research results. However, since the cost of taking vitamin C is low and it is relatively safe, cold patients may wish to give it a try, at least there will be no side effects.
6. Low-fat food is the best weight-loss food
Many people who are on a diet will choose low-fat foods. Since dieting cannot lose weight, the legends about low-fat foods are not credible either. The main reason is that low-fat foods cannot bring satisfaction to the body while providing low energy. Counting calories is not as good as developing good living habits. A balanced diet can bring us health and fitness at the same time.
According to the report, readers may be at a loss after reading this article. Could it be that the nutrition legends that people believed in in the past were just broken? In fact, everything is changing, and so are scientific nutritional concepts. Since everyone is bound to make mistakes, it is normal to make mistakes when it comes to eating. The important thing is to adjust your diet according to your own situation from now on and find the healthy eating habits that best suit you. (Compiled/Liu Lifei)
